Constructor Detail

SynchronizedBlock

public SynchronizedBlock(LocalInfo local)

Method Detail

setBodyBlock

public void setBodyBlock(StructuredBlock body)

Sets the body block.

getSubBlocks

public StructuredBlock[] getSubBlocks()

Returns all sub block of this structured block.

Overrides:

getSubBlocks in class StructuredBlock

replaceSubBlock

public boolean replaceSubBlock(StructuredBlock oldBlock,
                               StructuredBlock newBlock)

Replaces the given sub block with a new block.

Overrides:

replaceSubBlock in class StructuredBlock

Parameters:

oldBlock - the old sub block.

newBlock - the new sub block.

Returns:

false, if oldBlock wasn't a direct sub block.

getDeclarables

public java.util.Set getDeclarables()

Overrides:

getDeclarables in class StructuredBlock

dumpInstruction

public void dumpInstruction(TabbedPrintWriter writer)
                     throws java.io.IOException

Description copied from class: StructuredBlock

Print the instruction expressing this structured block.

Specified by:

dumpInstruction in class StructuredBlock

Parameters:

writer - The tabbed print writer, where we print to.

Throws:

java.io.IOException

simplify

public void simplify()

Overrides:

simplify in class StructuredBlock

jumpMayBeChanged

public boolean jumpMayBeChanged()

Determines if there is a sub block, that flows through to the end of this block. If this returns true, you know that jump is null.

Overrides:

jumpMayBeChanged in class StructuredBlock

Returns:

true, if the jump may be safely changed.

doTransformations

public boolean doTransformations()

Description copied from class: StructuredBlock

Do simple transformation on the structuredBlock.

Overrides:

doTransformations in class StructuredBlock

Returns:

true, if some transformation was done.
