Class BitMaskTextProp

java.lang.Object

org.apache.poi.hslf.model.textproperties.TextProp

org.apache.poi.hslf.model.textproperties.BitMaskTextProp

All Implemented Interfaces:

Duplicatable, GenericRecord

Direct Known Subclasses:

CharFlagsTextProp, ParagraphFlagsTextProp, WrapFlagsTextProp

public abstract class BitMaskTextProp
extends TextProp

Definition of a special kind of property of some text, or its paragraph. For these properties, a flag in the "contains" header field tells you the data property family will exist. The value of the property is itself a mask, encoding several different (but related) properties

BitMaskTextProp

protected BitMaskTextProp(int sizeOfDataBlock,
                          int maskInHeader,
                          String overallName,
                          String... subPropNames)

Method Detail

getSubPropNames

public String[] getSubPropNames()

Fetch the list of the names of the sub properties

getSubPropMatches

public boolean[] getSubPropMatches()

Fetch the list of if the sub properties match or not

getWriteMask

public int getWriteMask()

Calculate mask from the subPropMatches.

Overrides:

getWriteMask in class TextProp

setWriteMask

public void setWriteMask(int writeMask)

Sets the write mask, i.e. which defines the text properties to be considered

Parameters:

writeMask - the mask, bit values outside the property mask range will be ignored

getValue

public int getValue()

Return the text property value. Clears all bits of the value, which are marked as unset.

Overrides:

getValue in class TextProp

Returns:

the text property value.

setValue

public void setValue(int val)

Set the value of the text property, and recompute the sub properties based on it, i.e. all unset subvalues will be cleared. Use setSubValue(boolean, int) to explicitly set subvalues to false.

Overrides:

setValue in class TextProp

setValueWithMask

public void setValueWithMask(int val,
                             int writeMask)

Convenience method to set a value with mask, without splitting it into the subvalues

getSubValue

public boolean getSubValue(int idx)

Fetch the true/false status of the subproperty with the given index

setSubValue

public void setSubValue(boolean value,
                        int idx)

Set the true/false status of the subproperty with the given index

cloneAll

public BitMaskTextProp cloneAll()

Returns:

an identical copy of this, i.e. also the subPropMatches are copied

getGenericProperties

public Map<String,Supplier<?>> getGenericProperties()

Specified by:

getGenericProperties in interface GenericRecord

Overrides:

getGenericProperties in class TextProp

copy

public abstract BitMaskTextProp copy()

Description copied from class: TextProp

Clone, eg when you want to actually make use of one of these.

Specified by:

copy in interface Duplicatable

Overrides:

copy in class TextProp
