Argumentscljprotocol
Implemented by Directive.
Implemented by [[Directive]].
argumentsclj
(arguments element)Returns a map of keyword name to argument value. May return nil if no arguments.
The value may reflect query variables or argument defaults.
Returns a map of keyword name to argument value. May return nil if no arguments. The value may reflect query variables or argument defaults.
Directivecljprotocol
Implements Arguments.
Implements [[Arguments]].
directive-typeclj
(directive-type d)Returns the type of directive as a keyword.
Returns the type of directive as a keyword.
Directivescljprotocol
An element that may contain directives.
An element that may contain directives.
directivesclj
(directives element)Returns a map of directives for this element; keys are keywords identifying
the directive, values are a seq of Directive of that type (directives
are inherently repeatable).
May return nil.
Returns a map of directives for this element; keys are keywords identifying the directive, values are a seq of [[Directive]] of that type (directives are inherently repeatable). May return nil.
Fieldcljprotocol
A field within a Type. Implements Directives and QualifiedName.
A field within a [[Type]]. Implements [[Directives]] and [[QualifiedName]].
root-type-nameclj
(root-type-name field)Returns the keyword name of root type of the field.
Returns the keyword name of root type of the field.
Fieldscljprotocol
Implemented by the :object and :interface Type kinds to expose fields.
Implemented by the :object and :interface [[Type]] kinds to expose fields.
fieldsclj
(fields type)Returns a map of keyword to Field.
Returns a map of keyword to [[Field]].
FieldSelectioncljprotocol
A SelectionSet that extracts a value from a field and records it into the
result as a name or alias; for non-scalar types, may have sub-selections.
Also implements QualifiedName, Arguments, and Directives.
Directives here are the directives on the selection (the executable directives); access the underlying field to get the type system directives.
A [[SelectionSet]] that extracts a value from a field and records it into the result as a name or alias; for non-scalar types, may have sub-selections. Also implements [[QualifiedName]], [[Arguments]], and [[Directives]]. Directives here are the directives on the selection (the executable directives); access the underlying field to get the type system directives.
alias-nameclj
(alias-name fs)Returns the alias for the field selection, or name of the field.
Returns the alias for the field selection, or name of the field.
fieldclj
(field fs)Returns the field actually selected, a Field.
Returns the field actually selected, a [[Field]].
field-nameclj
(field-name fs)Returns the name of the field (as an unqualified keyword).
Returns the name of the field (as an unqualified keyword).
root-value-typeclj
(root-value-type fs)Returns the root value type for this field (the actual type may
include list or non-null qualifiers).
Returns the root value type for this field (the actual type may include `list` or `non-null` qualifiers).
QualifiedNamecljprotocol
qualified-nameclj
(qualified-name named)Returns a keyword whose namespace is the containing element; e.g., :User/id for the id field of the User type.
Returns a keyword whose namespace is the containing element; e.g., :User/id for the id field of the User type.
SelectionSetcljprotocol
An selection that may contain sub-selections.
An selection that may contain sub-selections.
selection-kindclj
(selection-kind selection)The type of selection: either :field, :inline-fragment or :named-fragment.
For :field, the FieldSelection protocol will also be implemented.
The type of selection: either :field, :inline-fragment or :named-fragment. For :field, the [[FieldSelection]] protocol will also be implemented.
selectionsclj
(selections selection)Returns a seq of sub-selections (also SelectionSets) of this selection.
May be nil for a field that selects a scalar.
Returns a seq of sub-selections (also SelectionSets) of this selection. May be nil for a field that selects a scalar.
Typecljprotocol
A type defined in a GraphQL schema. Implements the Directives protocol as well.
A type defined in a GraphQL schema. Implements the [[Directives]] protocol as well.
type-kindclj
(type-kind type)Returns the kind of type, one of: :object, :union, :interface, :scalar, or :enum.
Returns the kind of type, one of: `:object`, `:union`, `:interface`, `:scalar`, or `:enum`.
type-nameclj
(type-name type)Returns the name of the type, as a keyword.
Returns the name of the type, as a keyword.
