ArrayGetStringPart()

Purpose:

FCJSon::ArrayGetStringPart() gets a partial alpha value from an array object.

Usage:

aval = FCJSon::ArrayGetStringPart(<jsonident>,<arrayidx>, <stridx> [, <key> ]);

Arguments:

integer <jsonident> - A valid json array ident.

integer <arrayidx> - The 0 based index into the json array.

integer <stridx> - The 0 based index into the string to rtn

alpha <key> - Optional. Use <key> if the object at <arrayidx> is a json object of <key>:<value> pairs and it contains an alpha identified by <key>. If the object in the array at idx arrayidx is an alpha value, then you should not specify <key> when calling FCCom::ArrayGetStringPart()

Returns:

alpha <aval> - A 4c alpha value.

If this value is equal to "", then there is nothing left in the string to return.

Where Used:

FCJSon::ArrayGetStringPart() can be called from anywhere.

Description:

FCJSon::ArrayGetStringPart() gets a partial alpha value from an array object or from an json object in an array. When getting the value directly from the array, no <key> should be specified. When getting the value from a json object embedded in the array, you must specify the <key> parameter to FCJSon::ArrayGetStringPart().

The value returned will be truncated to fit in <aval>

The purpose of this function is to allow retrieval of alpha values that exceed the maximum 4C alpha length.
