PercentLength
public PercentLength(double factor, PercentBase lbase)
Main constructor. Construct an object based on a factor (the percent, as a factor) and an object which has a method to return the Length which provides the "base" for the actual length that is modeled.- Parameters:
factor
- the percentage factor, expressed as a decimal (e.g. use .95 to represent 95%)lbase
- base property to which the factor should be applied
-

Method Detail
-
getBaseLength
public PercentBase getBaseLength()
- Returns:
- the base
-
getPercentage
protected double getPercentage()
Used during property resolution to check for negative percentages- Returns:
- the percentage value
-
isAbsolute
public boolean isAbsolute()
Return false because percent-length are always relative. Return true if the numeric is an absolute value. Relative values are percentages and table-column-units. All other numerics are absolute.- Returns:
- true when the numeric is absolute.
-
getNumericValue
public double getNumericValue()
Return the value of this Numeric- Returns:
- the computed value.
-
getNumericValue
public double getNumericValue(PercentBaseContext context)
Return the value of this Numeric- Parameters:
context
- The context for the length calculation (for percentage based lengths)- Returns:
- the computed value.
-
getString
public java.lang.String getString()
This method expects to be overridden by subclasses.
-
getValue
public int getValue()
Return the length of this PercentLength. Returns the length in 1/1000ths of a point (millipoints)- Returns:
- the length in millipoints
-
getValue
public int getValue(PercentBaseContext context)
Returns the length in 1/1000ths of a point (millipoints)- Parameters:
context
- The context for the length calculation (for percentage based lengths)- Returns:
- the length in millipoints
