Method Details
-
processQuantity
Description copied from interface:MicroPropsGenerator
Considers the givenDecimalQuantity
, optionally mutates it, and returns aMicroProps
.- Specified by:
processQuantity
in interfaceMicroPropsGenerator
- Parameters:
quantity
- The quantity for consideration and optional mutation.- Returns:
- A MicroProps instance resolved for the quantity.
-
getMultiplier
public int getMultiplier(int magnitude) Description copied from interface:MultiplierProducer
Maps a magnitude to a multiplier in powers of ten. For example, in compact notation in English, a magnitude of 5 (e.g., 100,000) should return a multiplier of -3, since the number is displayed in thousands.- Specified by:
getMultiplier
in interfaceMultiplierProducer
- Parameters:
magnitude
- The power of ten of the input number.- Returns:
- The shift in powers of ten.
-
getPrefixLength
public int getPrefixLength()Description copied from interface:Modifier
Gets the length of the prefix. This information can be used in combination withModifier.apply(com.ibm.icu.impl.FormattedStringBuilder, int, int)
to extract the prefix and suffix strings.- Specified by:
getPrefixLength
in interfaceModifier
- Returns:
- The number of characters (UTF-16 code units) in the prefix.
-
getCodePointCount
public int getCodePointCount()Description copied from interface:Modifier
Returns the number of code points in the modifier, prefix plus suffix.- Specified by:
getCodePointCount
in interfaceModifier
-
isStrong
public boolean isStrong()Description copied from interface:Modifier
Whether this modifier is strong. If a modifier is strong, it should always be applied immediately and not allowed to bubble up. With regard to padding, strong modifiers are considered to be on the inside of the prefix and suffix. -
containsField
Description copied from interface:Modifier
Whether the modifier contains at least one occurrence of the given field.- Specified by:
containsField
in interfaceModifier
-
getParameters
Description copied from interface:Modifier
Gets a set of "parameters" for this Modifier.- Specified by:
getParameters
in interfaceModifier
-
strictEquals
Description copied from interface:Modifier
Returns whether this Modifier equals another Modifier.- Specified by:
strictEquals
in interfaceModifier
-
apply
Description copied from interface:Modifier
Apply this Modifier to the string builder.- Specified by:
apply
in interfaceModifier
- Parameters:
output
- The string builder to which to apply this modifier.leftIndex
- The left index of the string within the builder. Equal to 0 when only one number is being formatted.rightIndex
- The right index of the string within the string builder. Equal to length when only one number is being formatted.- Returns:
- The number of characters (UTF-16 code units) that were added to the string builder.
