Defines the protocols for allocating an manipulating blocks

Block clj/s protocol

An abstraction over a block of raw binary data of fixed length

put-longs! clj/s

(put-longs! this offset len values)

Modifies the longs at a given offset within the block. Offset is in Longs.

get-bytes clj/s

(get-bytes this offset len)

Returns the bytes at a given offset within the block.

put-byte! clj/s

(put-byte! this offset value)

Modifies the byte at a given offset within the block.

put-long! clj/s

(put-long! this offset value)

Modifies the long at a given offset within the block. Offset is in Longs.

get-int clj/s

(get-int this offset)

Returns the integer at a given offset within the block. Offset is in Integers.

put-ints! clj/s

(put-ints! this offset len values)

Modifies the ints at a given offset within the block. Offset is in Integers.

put-bytes! clj/s

(put-bytes! this offset len values)

Modifies the bytes at a given offset within the block.

get-longs clj/s

(get-longs this offset len)

Returns the longs at a given offset within the block. Offset is in Longs.

get-byte clj/s

(get-byte this offset)

Returns the byte at a given offset within the block.

put-block! clj/s

(put-block! this offset src)

(put-block! this offset src src-offset length)

Copies the contents of one block into this block.

get-ints clj/s

(get-ints this offset len)

Returns the ints at a given offset within the block. Offset is in Integers.

get-long clj/s

(get-long this offset)

Returns the long at a given offset within the block. Offset is in Longs.

copy-over! clj/s

(copy-over! this src src-offset)

Replace the contents of this block with another (starting at an offset on the source).

put-int! clj/s

(put-int! this offset value)

Modifies the integer at a given offset within the block. Offset is in Integers.

get-id clj/s

(get-id this)

Returns the ID of the block.

BlockManager clj/s protocol

A mutating object for allocating blocks

allocate-block! clj/s

(allocate-block! this)

Allocate a new block from the manager's resources.

copy-block! clj/s

(copy-block! this block)

Allocates a new block, initialized with a copy of another block.

copy-to-tx clj/s

(copy-to-tx this block)

Returns a block that is in the current transaction, possibly returning the current block

get-block clj/s

(get-block this id)

Returns the block associated with an ID.

get-block-size clj/s

(get-block-size this)

Returns the size of blocks allocated by this manager

write-block clj/s

(write-block this block)

Writes a block into the managed resources. Flushing is not expected.
