Detailed Description

Java implementation of string utility methods for use in Scheme calls. Used for ease of reasoning about the solution or to address issues with Kawa (e.g. memory problems). See runtime.scm

joinStrings()

static String com.google.appinventor.components.runtime.util.JavaStringUtils.joinStrings ( List< Object >  listOfStrings, String  separator  )

static

Java implementation of join-strings since the Kawa version appears to run of space. See runtime.scm

The elements in listOString are Kawa strings, but these are not necessarily Java Strings. They might be FStrings. So we accept a list of Objects and use toString to do a conversion.

Implements the following operation

(define join-strings (strings separator) (JavaJoinListOfStrings:joinStrings strings separator))

I'm writing this in Java, rather than using Kawa in runtime.scm because Kawa seems to blow out memory (or stack?) on small-memory systems and large lists.

replaceAllMappings()

static String com.google.appinventor.components.runtime.util.JavaStringUtils.replaceAllMappings ( String  text, Map< Object, Object >  mappings, MappingOrder  order  )

static

Replaces the specified text string with the specified mappings, which is a map containing Key Value pairs where the key is the substring to replace, and the value is the value to replace the substring with. An order parameter is specified to indicate the order of mapping applications.

Parameters

text	Text to apply mappings to
mappings	Map containing mappings
order	Order to use for replacing mappings

Returns

Text with the mappings applied

replaceAllMappingsDictionaryOrder()

static String com.google.appinventor.components.runtime.util.JavaStringUtils.replaceAllMappingsDictionaryOrder ( String  text, Map< Object, Object >  mappings  )

static

Replaces the specified text string with the specified mappings in dictionary element order.

text	Text to apply mappings to
mappings	Map containing mappings

Returns

Text with the mappings applied

static String com.google.appinventor.components.runtime.util.JavaStringUtils.replaceAllMappingsEarliestOccurrenceOrder ( String  text, Map< Object, Object >  mappings  )
