Method Detail

addDelimiters

public static java.lang.String addDelimiters(java.lang.String s)

Adds end delimiter or block delimiters to the string.

checkBlockStructure

public static int[] checkBlockStructure(java.lang.String s)

Checks parse errors in block delimiters.

Returns an array of two int:

[0] = The number of CLOSE_BLOCK without OPEN_BLOCK

[1] = The number of missing CLOSE_BLOCK at the end of the string

Both values must be equal to 0 for the string to be correct.

extractSection

public static java.lang.String extractSection(java.lang.String script,
                                              java.lang.String sectionName)

Returns a section of the script, null if not found.

indent

public static java.lang.String indent(java.lang.String s)

indent

public static java.lang.String indent(java.lang.String s,
                                      boolean addTabs,
                                      boolean addLinebreaks)

Idents a string

indexOfCloseBlock

public static int indexOfCloseBlock(java.lang.String s)

Returns the index of closing block, ignoring lower level blocks. Returns -1 if not found.

leftRightsScript

public static java.lang.String leftRightsScript(java.lang.String[] leftrights,
                                                java.lang.String operator)

TESTED Fusions [left][right][left][right] items (without delimiters) in one string with delimiters.

listElements

public static java.lang.String[] listElements(java.lang.String listScript)

Breaks a list of items into separate strings. Separators are kept.

listLeftRights

public static java.lang.String[] listLeftRights(java.lang.String listScript,
                                                java.lang.String operator)

TESTED Breaks a list of items in the form [left][operator][right][separator] into a string array in the form [left][right][left][right]... Separators are removed.

listScript

public static java.lang.String listScript(java.lang.String[] scripts)

Fusions items (with delimiters) in one string.

outsideIndexOf

public static int outsideIndexOf(java.lang.String s,
                                 java.lang.String search)

Returns the first occurrence of the specified string, ignoring all lower-level blocks.

s must not have parse errors

removeDelimiters

public static java.lang.String removeDelimiters(java.lang.String s)

Removes block and item delimiters from this string.

repairBlockStructure

public static java.lang.String repairBlockStructure(java.lang.String s)

Adds misleading block symbols in script.

Missing block delimiters ared usually added to bad strings to avoid parse error propagation:

"}a{{b}c{" -> "{# }a{{b}c{ #}}"

searchEnd

public static int searchEnd(java.lang.String s)

Searches for the item end (delimiter or close block) in string.

searchOperator

public static int searchOperator(java.lang.String s)

Searches for the the first operator in item: Returns the index of first non-alphanumeric character.

toScriptValue

public static java.lang.String toScriptValue(java.lang.Object value)

Returns the script form of a value. Examples:

"120" (Integer)

"120.58" (Float)

"abc" (String)

"true" (Boolean)

"[120, 55, 28]" (Integer array)

"[[2, 50], [3, 20]]" (2-dimensions Integer array)

etc.

Does not work with primitive arrays.

toStrings

public static java.lang.String[] toStrings(java.util.Vector v)

toValue

public static java.lang.Object toValue(java.lang.String genericValue,
                                       java.lang.Class type)

Returns the object form of a script value. Examples:

"120" (Integer)

"120.58" (Float)

"abc" (String)

"true", "yes" (Boolean)

"[120, 55, 28]" (Integer array)

"[[2, 50], [3, 20]]" (2-dimensions Integer array)

etc.
