public GroovyMapFormatter()

Method Detail

format

public static java.lang.String format(java.util.Map<?,?> map)

Formats a map to a Groovy-style string.

Example: [key: 'value', 'complex key': 'another value', key3: null]

format

public static java.lang.String format(java.util.Map.Entry<?,?> entry)

Formats a map entry to a Groovy-style string.

Example: key: 'value', 'complex key': 'another value', key3: null

parse

public static java.util.Map<java.lang.String,java.lang.String> parse(java.lang.String s)

Convenience wrapper that parses a Groovy-style map string into a LinkedHashMap.

parseEntry

public static java.util.Map.Entry<java.lang.String,java.lang.String> parseEntry(java.lang.String s)

Parses a Groovy-style map string into a single Map.Entry.

Parameters:

s - The string to parse (e.g. "key: 'value'" or "[key: 'value']")

Returns:

A Map.Entry, or null if the string is empty or represents an empty map.

Throws:

java.lang.IllegalArgumentException - if the string contains more than one entry.

doParse

public static int doParse(java.lang.CharSequence s,
                          int startPos,
                          java.util.function.BiConsumer<java.lang.String,java.lang.String> consumer)

The actual parser engine.

Iterates through a CharSequence starting at startPos, extracting key-value pairs and feeding them to the provided BiConsumer.

Returns:

The final position index after the map is fully parsed.
