class:FieldPosition [NONE]


  • public class FieldPosition
    extends Object
    
    FieldPosition is a simple class used by Format and its subclasses to identify fields in formatted output. Fields can be identified in two ways:
    • By an integer constant, whose names typically end with _FIELD. The constants are defined in the various subclasses of Format.
    • By a Format.Field constant, see ERA_FIELD and its friends in DateFormat for an example.

    FieldPosition keeps track of the position of the field within the formatted output with two indices: the index of the first character of the field and the index of the last character of the field.

    One version of the format method in the various Format classes requires a FieldPosition object as an argument. You use this format method to perform partial formatting or to get information about the formatted output (such as the position of a field).

    If you are interested in the positions of all attributes in the formatted string use the Format method formatToCharacterIterator.

constructor:<init>(int) [NONE]

constructor:<init>(java.text.Format.Field) [NONE]

  • FieldPosition

    public FieldPosition​(Format.Field attribute)
    Creates a FieldPosition object for the given field constant. Fields are identified by constants defined in the various Format subclasses. This is equivalent to calling new FieldPosition(attribute, -1) .
    Parameters:
    attribute - Format.Field constant identifying a field
    Since:
    1.4

constructor:<init>(java.text.Format.Field,int) [NONE]

  • FieldPosition

    public FieldPosition​(Format.Field attribute,
                         int fieldID)
    Creates a FieldPosition object for the given field. The field is identified by an attribute constant from one of the Field subclasses as well as an integer field ID defined by the Format subclasses. Format subclasses that are aware of Field should give precedence to attribute and ignore fieldID if attribute is not null. However, older Format subclasses may not be aware of Field and rely on fieldID. If the field has no corresponding integer constant, fieldID should be -1.
    Parameters:
    attribute - Format.Field constant identifying a field
    fieldID - integer constant identifying a field
    Since:
    1.4

method:getFieldAttribute() [NONE]

  • getFieldAttribute

    public Format.Field getFieldAttribute()
    Returns the field identifier as an attribute constant from one of the Field subclasses. May return null if the field is specified only by an integer field ID.
    Returns:
    Identifier for the field
    Since:
    1.4

method:getField() [NONE]

  • getField

    public int getField()
    Retrieves the field identifier.
    Returns:
    the field identifier

method:getBeginIndex() [NONE]

  • getBeginIndex

    public int getBeginIndex()
    Retrieves the index of the first character in the requested field.
    Returns:
    the begin index

method:getEndIndex() [NONE]

  • getEndIndex

    public int getEndIndex()
    Retrieves the index of the character following the last character in the requested field.
    Returns:
    the end index

method:setBeginIndex(int) [NONE]

  • setBeginIndex

    public void setBeginIndex​(int bi)
    Sets the begin index. For use by subclasses of Format.
    Parameters:
    bi - the begin index
    Since:
    1.2

method:setEndIndex(int) [NONE]

  • setEndIndex

    public void setEndIndex​(int ei)
    Sets the end index. For use by subclasses of Format.
    Parameters:
    ei - the end index
    Since:
    1.2

method:equals(java.lang.Object) [NONE]

  • equals

    public boolean equals​(Object obj)
    Overrides equals
    Overrides:
    equals in class Object
    Parameters:
    obj - the reference object with which to compare.
    Returns:
    true if this object is the same as the obj argument; false otherwise.
    See Also:
    Object.hashCode(), HashMap

method:hashCode() [NONE]

method:toString() [NONE]

  • toString

    public String toString()
    Return a string representation of this FieldPosition.
    Overrides:
    toString in class Object
    Returns:
    a string representation of this object
