## org.apache.fop.layoutmgr
Class SpaceSpecifier

    java.lang.Object
      org.apache.fop.layoutmgr.SpaceSpecifier

All Implemented Interfaces:
  java.lang.Cloneable

public class SpaceSpecifier
extends java.lang.Object
implements java.lang.Cloneable

Accumulate a sequence of space-specifiers (XSL space type) on areas with a stacking constraint. Provide a way to resolve these into a single MinOptMax value.

Constructor Summary
`SpaceSpecifier(boolean startsReferenceArea)` Creates a new SpaceSpecifier.

Method Summary
`void` | `addSpace(SpaceVal space)` Add a new space to the sequence.
`void` | `clear()` Clear all space specifiers
`java.lang.Object` | `clone()`
`boolean` | `hasSpaces()` Indicates whether any space-specifiers have been added.
`MinOptMax` | `resolve(boolean endsReferenceArea)` Resolve the current sequence of space-specifiers, accounting for forcing values.
`java.lang.String` | `toString()`

Constructor Detail

### SpaceSpecifier

    public SpaceSpecifier(boolean startsReferenceArea)

  Creates a new SpaceSpecifier.

Parameters:
  `startsReferenceArea` - true if it starts a new reference area

Method Detail

### clone

    public java.lang.Object clone()

### clear

    public void clear()

  Clear all space specifiers

### hasSpaces

    public boolean hasSpaces()

  Indicates whether any space-specifiers have been added.

  Returns:
    true if any space-specifiers have been added.

### addSpace

    public void addSpace(SpaceVal space)

  Add a new space to the sequence. If this sequence starts a reference area, and the added space is conditional, and there are no non-conditional values in the sequence yet, then ignore it. Otherwise add it to the sequence.

  Parameters:
    `space` - the space to add.

### resolve

    public MinOptMax resolve(boolean endsReferenceArea)

  Resolve the current sequence of space-specifiers, accounting for forcing values.

  Parameters:
    `endsReferenceArea` - whether the sequence should be resolved at the trailing edge of reference area.
  Returns:
    the resolved value as a min/opt/max triple.

### toString

    public java.lang.String toString()
