Constructor Detail

LongLiteral

public LongLiteral(String payload,
                   int pos,
                   long value)

Method Detail

getLiteralValue

public TypedValue getLiteralValue()

Specified by:

getLiteralValue in class Literal

isCompilable

public boolean isCompilable()

Description copied from class: SpelNodeImpl

Check whether a node can be compiled to bytecode. The reasoning in each node may be different but will typically involve checking whether the exit type descriptor of the node is known and any relevant child nodes are compilable.

Overrides:

isCompilable in class SpelNodeImpl

Returns:

true if this node can be compiled to bytecode

generateCode

public void generateCode(MethodVisitor mv,
                         CodeFlow cf)

Description copied from class: SpelNodeImpl

Generate the bytecode for this node into the supplied visitor. Context info about the current expression being compiled is available in the codeflow object. For example it will include information about the type of the object currently on the stack.

Overrides:

generateCode in class SpelNodeImpl

Parameters:

mv - the ASM MethodVisitor into which code should be generated

cf - a context object with info about what is on the stack
