ChainedCodeBuilder

public ChainedCodeBuilder(CodeBuilder downstream,
 Consumer<CodeElement> consumer)

Method Details

startLabel

public Label startLabel()

Description copied from interface: CodeBuilder

Returns the label associated with the beginning of the current block. If the current CodeBuilder is not a "block" builder, such as those provided by CodeBuilder.block(Consumer) or CodeBuilder.ifThenElse(Consumer, Consumer), the current block will be the entire method body.

Specified by:

startLabel in interface CodeBuilder

Returns:

the label associated with the beginning of the current block

endLabel

public Label endLabel()

Description copied from interface: CodeBuilder

Returns the label associated with the end of the current block. If the current CodeBuilder is not a "block" builder, such as those provided by CodeBuilder.block(Consumer) or CodeBuilder.ifThenElse(Consumer, Consumer), the current block will be the entire method body.

Specified by:

endLabel in interface CodeBuilder

Returns:

the label associated with the end of the current block

allocateLocal

public int allocateLocal(TypeKind typeKind)

Description copied from interface: CodeBuilder

Returns the local variable slot of a fresh local variable. This method makes reasonable efforts to determine which slots are in use and which are not. When transforming a method, fresh locals begin at the maxLocals of the original method. For a method being built directly, fresh locals begin after the last parameter slot.

If the current code builder is a "block" code builder provided by CodeBuilder.block(Consumer), CodeBuilder.ifThen(Consumer), or CodeBuilder.ifThenElse(Consumer, Consumer), at the end of the block, locals are reset to their value at the beginning of the block.

Specified by:

allocateLocal in interface CodeBuilder

Parameters:

typeKind - the type of the local variable

Returns:

the local variable slot of a fresh local variable

with

public CodeBuilder with(CodeElement element)

Description copied from interface: ClassfileBuilder

Integrate the ClassfileElement into the entity being built.

Specified by:

with in interface ClassfileBuilder<CodeElement,CodeBuilder>

Parameters:

element - the element

Returns:

this builder
