public AttrMap()

Method Detail

isOn

public boolean isOn(java.lang.String key,
                    boolean defaultValue)

Method to determine if this map has the attribute defined by key turned on, or if the key is not present, return the default value.

Parameters:

key - the attribute being sought.

defaultValue - the value to return if this map does not contain key, or if the stored value is null.

Returns:

true if the attribute defined by key is turned on or, if the attribute is not present in the map (or has a null value), then return the default value.

isOn

public boolean isOn(java.lang.String key)

Method to determine if this map has the attribute defined by key turned on, or if the key is not present, return a default value based on the key.

Parameters:

key - the attribute being sought.

Returns:

if this map contains key, then its "on" state is returned, defaulting to true; otherwise, if key is $AttrNormalize return false; else if key is $AttrRound or $AttrZeroreturn true; failing that, return false.

getInt

public int getInt(java.lang.String key,
                  int defaultValue)

Method to determine for this map the integer value of the attribute defined by key, or if the key is not present, the default value. This method is parallel to isOn(String,boolean).

Parameters:

key - the attribute being sought.

defaultValue - the value to return if this map does not contain key.

Returns:

the integer value of the attribute defined by key or, if the attribute is not present in the map, then return the default value.

getInt

public int getInt(java.lang.String key)

Method to determine for this map the integer value of the attribute defined by key, or if the attribute is not present, a default value, determined according to the value of key. This method is parallel to isOn(String).

Parameters:

key - the attribute being sought.

Returns:

the integer value of the attribute defined by key or, if the attribute is not present in the map, then: if key is $AttrPlaces, then -1 (show all places); else if key is $AttrRadix, then 10; otherwise, return 0.

getDouble

public double getDouble(java.lang.String key,
                        double defaultValue)

Method to determine for this map the double value of the attribute defined by key, or if the key is not present, the default value. This method is parallel to isOn(String,boolean).

Parameters:

key - the attribute being sought.

defaultValue - the value to return if this map does not contain key.

Returns:

the double value of the attribute defined by key or, if the attribute is not present in the map, then return the default value.

getDouble

public double getDouble(java.lang.String key)

Method to determine for this map the double value of the attribute defined by key, or if the attribute is not present, a default value, determined according to the value of key. This method is parallel to isOn(String).

Parameters:

key - the attribute being sought.

Returns:

the double value of the attribute defined by key or, if the attribute is not present in the map, then: return 0.

getString

public java.lang.String getString(java.lang.String key,
                                  java.lang.String defaultValue)

Method to determine for this map the string value of the attribute defined by key, or if the key is not present, the default value. This method is parallel to isOn(String,boolean).

Parameters:

key - the attribute being sought.

defaultValue - the value to return if this map does not contain key.

Returns:

the string value of the attribute defined by key or, if the attribute is not present in the map, then return the default value.

getString

public java.lang.String getString(java.lang.String key)

Method to determine for this map the string value of the attribute defined by key, or if the attribute is not present, a default value, determined according to the value of key. This method is parallel to isOn(String).

Parameters:

key - the attribute being sought.

Returns:

the string value of the attribute defined by key or, if the attribute is not present in the map, then: if key is $AttrDecimal, then "."; otherwise, return null.

setBoolean

public void setBoolean(java.lang.String key,
                       boolean value)

Method to set int attribute defined by key.

Parameters:

key - the attribute being set.

value - the value to set.

setInt

public void setInt(java.lang.String key,
                   int value)

Method to set int attribute defined by key.

Parameters:

key - the attribute being set.

value - the value to set.

setDouble

public void setDouble(java.lang.String key,
                      double value)

Method to set int attribute defined by key.

Parameters:

key - the attribute being set.

value - the value to set.
