public class CorrespondingPropertyMaker
extends java.lang.Object


Field Summary
protected  PropertyMaker baseMaker
           
protected  int lr_tb
           
protected  int rl_tb
           
protected  int tb_rl
           
protected  boolean useParent
           
 
Constructor Summary
CorrespondingPropertyMaker(PropertyMaker baseMaker)
           
 
Method Summary
 Property compute(PropertyList propertyList)
          Return a Property object representing the value of this property, based on other property values for this FO.
protected  PropertyList getWMPropertyList(PropertyList pList)
          Return the property list to use for fetching writing mode depending property ids.
 boolean isCorrespondingForced(PropertyList propertyList)
          For properties that operate on a relative direction (before, after, start, end) instead of an absolute direction (top, bottom, left, right), this method determines whether a corresponding property is specified on the corresponding absolute direction.
 void setCorresponding(int lr_tb, int rl_tb, int tb_rl)
           
 void setRelative(boolean relative)
           
 void setUseParent(boolean useParent)
          Controls whether the PropertyMaker accesses the parent property list or the current property list for determining the writing mode.

useParent

protected boolean useParent
Constructor Detail

CorrespondingPropertyMaker

public CorrespondingPropertyMaker(PropertyMaker baseMaker)
Method Detail

setCorresponding

public void setCorresponding(int lr_tb,
                             int rl_tb,
                             int tb_rl)

setUseParent

public void setUseParent(boolean useParent)
Controls whether the PropertyMaker accesses the parent property list or the current property list for determining the writing mode.

Parameters:
useParent - true if the parent property list should be used.

setRelative

public void setRelative(boolean relative)

isCorrespondingForced

public boolean isCorrespondingForced(PropertyList propertyList)
For properties that operate on a relative direction (before, after, start, end) instead of an absolute direction (top, bottom, left, right), this method determines whether a corresponding property is specified on the corresponding absolute direction. For example, the border-start-color property in a lr-tb writing-mode specifies the same thing that the border-left-color property specifies. In this example, if the Maker for the border-start-color property is testing, and if the border-left-color is specified in the properties, this method should return true.

Parameters:
propertyList - collection of properties to be tested
Returns:
true iff 1) the property operates on a relative direction, AND 2) the property has a corresponding property on an absolute direction, AND 3) the corresponding property on that absolute direction has been specified in the input properties

compute

public Property compute(PropertyList propertyList)
                 throws PropertyException
Return a Property object representing the value of this property, based on other property values for this FO. A special case is properties which inherit the specified value, rather than the computed value.

Parameters:
propertyList - The PropertyList for the FO.
Returns:
Property A computed Property value or null if no rules are specified (in foproperties.xml) to compute the value.
Throws:
FOPException - for invalid or inconsistent FO input
PropertyException

getWMPropertyList

protected PropertyList getWMPropertyList(PropertyList pList)
Return the property list to use for fetching writing mode depending property ids.
