jdk.lang.reflect.Parameter — clojure-interop/java.lang.reflect 1.0.5

Information about method parameters.

A Parameter provides information about method parameters, including its name and modifiers. It also provides an alternate means of obtaining attributes for the parameter.

equals clj

(equals this obj)

Compares based on the executable and the index.

obj - The object to compare. - java.lang.Object

returns: Whether or not this is equal to the argument. - boolean

get-annotated-type clj

(get-annotated-type this)

Returns an AnnotatedType object that represents the use of a type to specify the type of the formal parameter represented by this Parameter.

returns: an AnnotatedType object representing the use of a type to specify the type of the formal parameter represented by this Parameter - java.lang.reflect.AnnotatedType

get-annotation clj

(get-annotation this annotation-class)

Returns this element's annotation for the specified type if such an annotation is present, else null.

annotation-class - the Class object corresponding to the annotation type - java.lang.Class

returns: this element's annotation for the specified annotation type if present on this element, else null - <T extends java.lang.annotation.Annotation> T

throws: java.lang.NullPointerException - if the given annotation class is null

get-annotations clj

(get-annotations this)

Returns annotations that are present on this element.

If there are no annotations present on this element, the return value is an array of length 0.

The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.

returns: annotations present on this element - java.lang.annotation.Annotation[]

get-annotations-by-type clj

(get-annotations-by-type this annotation-class)

Returns annotations that are associated with this element.

If there are no annotations associated with this element, the return value is an array of length 0.

The difference between this method and AnnotatedElement.getAnnotation(Class) is that this method detects if its argument is a repeatable annotation type (JLS 9.6), and if so, attempts to find one or more annotations of that type by "looking through" a container annotation.

The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.

annotation-class - the Class object corresponding to the annotation type - java.lang.Class

returns: all this element's annotations for the specified annotation type if associated with this element, else an array of length zero - <T extends java.lang.annotation.Annotation> T[]

throws: java.lang.NullPointerException - if the given annotation class is null

get-declared-annotation clj

(get-declared-annotation this annotation-class)

Description copied from interface: AnnotatedElement

annotation-class - the Class object corresponding to the annotation type - java.lang.Class

returns: this element's annotation for the specified annotation type if directly present on this element, else null - <T extends java.lang.annotation.Annotation> T

throws: java.lang.NullPointerException - if the given annotation class is null

get-declared-annotations clj

(get-declared-annotations this)

Returns annotations that are directly present on this element. This method ignores inherited annotations.

If there are no annotations directly present on this element, the return value is an array of length 0.

The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.

returns: annotations directly present on this element - java.lang.annotation.Annotation[]

get-declared-annotations-by-type clj

(get-declared-annotations-by-type this annotation-class)

Description copied from interface: AnnotatedElement

annotation-class - the Class object corresponding to the annotation type - java.lang.Class

returns: all this element's annotations for the specified annotation type if directly or indirectly present on this element, else an array of length zero - <T extends java.lang.annotation.Annotation> T[]

throws: java.lang.NullPointerException - if the given annotation class is null

get-declaring-executable clj

(get-declaring-executable this)

Return the Executable which declares this parameter.

returns: The Executable declaring this parameter. - java.lang.reflect.Executable

get-modifiers clj

(get-modifiers this)

Get the modifier flags for this the parameter represented by this Parameter object.

returns: The modifier flags for this parameter. - int

get-name clj

(get-name this)

Returns the name of the parameter. If the parameter's name is present, then this method returns the name provided by the class file. Otherwise, this method synthesizes a name of the form argN, where N is the index of the parameter in the descriptor of the method which declares the parameter.

returns: The name of the parameter, either provided by the class file or synthesized if the class file does not provide a name. - java.lang.String

get-parameterized-type clj

(get-parameterized-type this)

Returns a Type object that identifies the parameterized type for the parameter represented by this Parameter object.

returns: a Type object identifying the parameterized type of the parameter represented by this object - java.lang.reflect.Type

get-type clj

(get-type this)

Returns a Class object that identifies the declared type for the parameter represented by this Parameter object.

returns: a Class object identifying the declared type of the parameter represented by this object - java.lang.Class<?>

hash-code clj

(hash-code this)

Returns a hash code based on the executable's hash code and the index.

returns: A hash code based on the executable's hash code. - int

implicit? clj

(implicit? this)

Returns true if this parameter is implicitly declared in source code; returns false otherwise.

returns: true if and only if this parameter is implicitly declared as defined by The Java™ Language Specification. - boolean

name-present? clj

(name-present? this)

Returns true if the parameter has a name according to the class file; returns false otherwise. Whether a parameter has a name is determined by the MethodParameters attribute of the method which declares the parameter.

returns: true if and only if the parameter has a name according to the class file. - boolean

synthetic? clj

(synthetic? this)

Returns true if this parameter is neither implicitly nor explicitly declared in source code; returns false otherwise.

returns: true if and only if this parameter is a synthetic construct as defined by The Java™ Language Specification. - boolean

to-string clj

(to-string this)

Returns a string describing this parameter. The format is the modifiers for the parameter, if any, in canonical order as recommended by The Java™ Language Specification, followed by the fully- qualified type of the parameter (excluding the last [] if the parameter is variable arity), followed by "..." if the parameter is variable arity, followed by a space, followed by the name of the parameter.

returns: A string representation of the parameter and associated information. - java.lang.String

var-args? clj

(var-args? this)

Returns true if this parameter represents a variable argument list; returns false otherwise.

returns: true if an only if this parameter represents a variable argument list. - boolean
