Method Detail

getIndex

public int getIndex()

Get the index of this location in the enclosing syntax tree. Every location has a unique index.

Returns:

getEnclosingTree

public SyntaxTree getEnclosingTree()

Get the enclosing syntax tree of this location.

Returns:

getType

public Type getType()

Get the declared type of this location. This is a convenience method since, in most cases, we are working on locations that have exactly one type.

Returns:

getType

public Type getType(int i)

Get a specific type of this location.

Returns:

getTypes

public Type[] getTypes()

Get the types for this location.

Returns:

numberOfTypes

public int numberOfTypes()

Get the number of types declared by this location.

Returns:

getBytecode

public T getBytecode()

Get the bytecode associated with this location

Returns:

getOpcode

public int getOpcode()

Get the underlying opcode for this location

Returns:

numberOfOperands

public int numberOfOperands()

Get the number of operand groups in this location.

Returns:

getOperand

public SyntaxTree.Location<?> getOperand(int i)

Return the ith operand associated with this location.

Parameters:

i -

Returns:

getOperands

public SyntaxTree.Location<?>[] getOperands()

Return the ith operand associated with this location.

Parameters:

i -

Returns:

numberOfOperandGroups

public int numberOfOperandGroups()

Get the number of operand groups in this location.

Returns:

getOperandGroup

public SyntaxTree.Location<?>[] getOperandGroup(int i)

Get the ith operand group in this location.

Parameters:

i -

Returns:

numberOfBlocks

public int numberOfBlocks()

Get the number of blocks contained in this statement. This includes only those which are immediate children of this statement, but not those which are transitively contained.

Returns:

getBlock

public SyntaxTree.Location<Bytecode.Block> getBlock(int i)

Get the ith block contained in this statement.

Parameters:

i -

Returns:

toString

public String toString()

Overrides:

toString in class Object
