Returns:

space-before value.

setSpaceBeforeCandidate

public void setSpaceBeforeCandidate(RtfAttributes candidate)

Sets a candidate for space-before property.

Parameters:

candidate - instance of RtfAttributes, considered as a candidate for space-before adding

setSpaceAfterCandidate

public void setSpaceAfterCandidate(RtfAttributes candidate)

Sets a candidate for space-after property.

Parameters:

candidate - instance of RtfAttributes, considered as a candidate for space-after adding

isBeforeCadidateSet

public boolean isBeforeCadidateSet()

Returns:

true, if candidate for space-before is set.

isAfterCadidateSet

public boolean isAfterCadidateSet()

Returns:

true, if candidate for space-after is set.

stopUpdatingSpaceBefore
