Class StringClauses

java.lang.Object

liquibase.util.StringClauses

public class StringClauses
extends Object

Defines a list of clauses that can be manipulated and rearranged based on keys associated with each. On toString(), the clauses will be joined by the separator passed at construction time and prepended/postpended by the start/end strings set at construction time.
Note: all keys and values passed in are trimmed.
NOTE: All keys are managed in a case INSENSITIVE manner
NOTE: Null or empty clauses and subclauses are skipped in toString()

Constructor Details

StringClauses

public StringClauses()

Creates a new StringClause with no start or end strings and a space separator.

StringClauses

public StringClauses(String separator)

Creates a new StringClause with no start or end strings and the given separator.

StringClauses

public StringClauses(String start,
 String separator,
 String end)

Creates a new StringClause with the given start, end and separator.

Method Details

append

public StringClauses append(String key,
 String clause)

Adds a new clause at the end of the list with the given key.

append

public StringClauses append(String key,
 StringClauses subclauses)

Adds a new sub-clause at the end of the list with the given key.

append

public StringClauses append(String clause)

Adds a new clause at the end of the list. The key is equal to the passed clause. There is no corresponding append with just a StringClauses because the subclause may not be fully created when appended and so the key may be an unexpected value.

append

public StringClauses append(Enum name,
 StringClauses subclauses)

Convenience method for append(String, StringClauses) when using enums.

append

public StringClauses append(Enum name,
 String clause)

Convenience method for append(String, String) when using enums.

append

public StringClauses append(StringClauses.LiteralClause literal)

prepend

public StringClauses prepend(StringClauses.LiteralClause literal)

prepend

public StringClauses prepend(String key,
 String clause)

Adds a clause with the given key to the beginning of the list.

prepend

public StringClauses prepend(String key,
 StringClauses clause)

Adds a sub-clause with the given key to the beginning of the list.

prepend

public StringClauses prepend(String clause)

Convenience method for prepend(String, String) that uses the clause as the key.

prepend
