## org.apache.fop.fo.properties
Class EnumNumber

    java.lang.Object
      org.apache.fop.fo.properties.Property
          org.apache.fop.fo.properties.EnumNumber

All Implemented Interfaces:
  Numeric

public final class EnumNumber
extends Property
implements Numeric

A number quantity in XSL which is specified as an enum, such as "no-limit".

Field Summary

`log`

Method Summary
`boolean` | `equals(java.lang.Object obj)`
`int` | `getDimension()` Return the dimension of this numeric. Plain numbers has a dimension of 0 and length has a dimension of 1. Other dimension can occur as a result of multiplications and divisions.
`int` | `getEnum()` This method expects to be overridden by subclasses
`static EnumNumber` | `getInstance(Property enumProperty)` Returns the canonical EnumNumber instance corresponding to the given Property
`Numeric` | `getNumeric()` This method expects to be overridden by subclasses
`double` | `getNumericValue()` Return the value of this Numeric logs an error, because it's not supposed to be called
`double` | `getNumericValue(PercentBaseContext context)` Return the value of this Numeric logs an error, because it's not supposed to be called
`java.lang.Object` | `getObject()` This method expects to be overridden by subclasses
`java.lang.String` | `getString()` This method expects to be overridden by subclasses.
`int` | `getValue()` Returns the value of this numeric as an int. logs an error, because it's not supposed to be called
`int` | `getValue(PercentBaseContext context)` Returns the value of this numeric as an int. logs an error, because it's not supposed to be called
`int` | `hashCode()`
`boolean` | `isAbsolute()` Return true if the numeric is an absolute value. Relative values are percentages and table-column-units. All other numerics are absolute. Always `true` for instances of this type

Method Detail

### getInstance

    public static EnumNumber getInstance(Property enumProperty)

  Returns the canonical EnumNumber instance corresponding to the given Property

  Parameters:
    `enumProperty` - the base EnumProperty
  Returns:
    the canonical instance

### getEnum

    public int getEnum()

  This method expects to be overridden by subclasses

  Specified by:
    `getEnum` in interface `Numeric`
  Overrides:
    `getEnum` in class `Property`
  Returns:
    integer equivalent of enumerated property value

### getString

    public java.lang.String getString()

  This method expects to be overridden by subclasses.

  Overrides:
    `getString` in class `Property`
  Returns:
    String property value

### getObject

    public java.lang.Object getObject()

  This method expects to be overridden by subclasses

  Overrides:
    `getObject` in class `Property`
  Returns:
    Object property value

### equals

    public boolean equals(java.lang.Object obj)

### hashCode

    public int hashCode()

### getDimension

    public int getDimension()

  Return the dimension of this numeric. Plain numbers has a dimension of 0 and length has a dimension of 1. Other dimension can occur as a result of multiplications and divisions.

  Specified by:
    `getDimension` in interface `Numeric`
  Returns:
    the dimension.

### isAbsolute

    public boolean isAbsolute()

  Return true if the numeric is an absolute value. Relative values are percentages and table-column-units. All other numerics are absolute. Always `true` for instances of this type

  Specified by:
    `isAbsolute` in interface `Numeric`
  Returns:
    true when the numeric is absolute.

### getNumericValue

    public double getNumericValue(PercentBaseContext context)
                           throws PropertyException

  Return the value of this Numeric logs an error, because it's not supposed to be called

  Specified by:
    `getNumericValue` in interface `Numeric`
  Parameters:
    `context` - The context for the length calculation (for percentage based lengths)
  Returns:
    the computed value.
  Throws:
    `PropertyException`

### getValue

    public int getValue(PercentBaseContext context)

  Returns the value of this numeric as an int. logs an error, because it's not supposed to be called

  Specified by:
    `getValue` in interface `Numeric`
  Parameters:
    `context` - the context for the length calculation (for percentage based lengths)
  Returns:
    the value as an integer.

### getValue

    public int getValue()

  Returns the value of this numeric as an int. logs an error, because it's not supposed to be called

  Specified by:
    `getValue` in interface `Numeric`
  Returns:
    the value as an integer.

### getNumericValue

    public double getNumericValue()

  Return the value of this Numeric logs an error, because it's not supposed to be called

  Specified by:
    `getNumericValue` in interface `Numeric`
  Returns:
    the computed value.

### getNumeric

    public Numeric getNumeric()

  This method expects to be overridden by subclasses

  Overrides:
    `getNumeric` in class `Property`
  Returns:
    Numeric property value
