Constructor Detail

ExceptionTable

public ExceptionTable(ConstPool cp)

Constructs an exception_table[].

Parameters: cp constant pool table.

add

public void add(int index, ExceptionTable table, int offset)

Copies the given exception table at the specified position in the table.

Parameters: index index (>= 0) at which the entry is to be inserted. offset the offset added to the code position.

add

public void add(int index, int start, int end, int handler, int type)

Adds a new entry at the specified position in the table.

Parameters: index index (>= 0) at which the entry is to be inserted. start startPc end endPc handler handlerPc type catchType

add

public void add(int start, int end, int handler, int type)

Appends a new entry at the end of the table.

Parameters: start startPc end endPc handler handlerPc type catchType

catchType

public int catchType(int nth)

Returns catchType of the n-th entry.

Parameters: nth the n-th (>= 0).

clone

public Object clone()

Creates and returns a copy of this object. The constant pool object is shared between this object and the cloned object.

copy

public ExceptionTable copy(ConstPool newCp, Map classnames)

Makes a copy of this exception_table[]. Class names are replaced according to the given Map object.

Parameters: newCp the constant pool table used by the new copy. classnames pairs of replaced and substituted class names.

endPc

public int endPc(int nth)

Returns endPc of the n-th entry.

Parameters: nth the n-th (>= 0).

handlerPc

public int handlerPc(int nth)

Returns handlerPc of the n-th entry.

Parameters: nth the n-th (>= 0).

remove

public void remove(int index)

Removes the entry at the specified position in the table.

Parameters: index the index of the removed entry.

setCatchType

public void setCatchType(int nth, int value)

Sets catchType of the n-th entry.

Parameters: nth the n-th (>= 0). value new value.

setEndPc

public void setEndPc(int nth, int value)

Sets endPc of the n-th entry.

Parameters: nth the n-th (>= 0). value new value.

setHandlerPc

public void setHandlerPc(int nth, int value)

Sets handlerPc of the n-th entry.

Parameters: nth the n-th (>= 0). value new value.

setStartPc

public void setStartPc(int nth, int value)

Sets startPc of the n-th entry.

Parameters: nth the n-th (>= 0). value new value.

size

public int size()

Returns exception_table_length, which is the number of entries in the exception_table[].

startPc

public int startPc(int nth)

Returns startPc of the n-th entry.

Parameters: nth the n-th (>= 0).
