CodeBuilder is a preview API of the Java platform.

Programs can only use CodeBuilder when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

A builder for code attributes (method bodies). Builders are not created directly; they are passed to handlers by methods such as MethodBuilder.withCode(Consumer)^PREVIEW or to code transforms. The elements of a code can be specified abstractly, by passing a CodeElement^PREVIEW to ClassFileBuilder.with(ClassFileElement)^PREVIEW or concretely by calling the various withXxx methods.

Method Details

original

Optional<CodeModelPREVIEW> original()

Returns the CodeModel^PREVIEW representing the method body being transformed, if this code builder represents the transformation of some CodeModel^PREVIEW.

Returns:

the CodeModel^PREVIEW representing the method body being transformed, if this code builder represents the transformation of some CodeModel^PREVIEW

newLabel

LabelPREVIEW newLabel()

Returns a fresh unbound label.

Returns:

a fresh unbound label

startLabel

LabelPREVIEW startLabel()

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

Returns:

the label associated with the beginning of the current block

endLabel

LabelPREVIEW endLabel()

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

Returns:

the label associated with the end of the current block

receiverSlot

int receiverSlot()

Returns the local variable slot associated with the receiver..

Returns:

the local variable slot associated with the receiver

Throws:

IllegalStateException - if this is not a static method

parameterSlot

int parameterSlot(int paramNo)

Returns the local variable slot associated with the specified parameter.. The returned value is adjusted for the receiver slot (if the method is an instance method) and for the requirement that long and double values require two slots.

Parameters:

paramNo - the index of the parameter

Returns:

the local variable slot associated with the specified parameter

allocateLocal

int allocateLocal(TypeKindPREVIEW typeKind)

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 block(Consumer), ifThen(Consumer), or ifThenElse(Consumer, Consumer), at the end of the block, locals are reset to their value at the beginning of the block.

Parameters:

typeKind - the type of the local variable

Returns:

the local variable slot of a fresh local variable

transforming
