Constant Field Values

NORMALIZE_NO_VOWELS_40_60

public static final int NORMALIZE_NO_VOWELS_40_60

Normalize name by removing vowels.

If the name has more than the maximum length characters, then strip all vowels from the 4th, 5th, etc. character of the original name. If the remaining length still exceeds the maximum length characters, then take the first 40% and last 60% off characters.

PObjDictionary

public PObjDictionary(Module[] modules,
                      int normalizeName)

Creates a new dictionary.

The ClassLoader for the database classes is guessed to be the same as the one for the PObjects library.

Method Detail

getNumModules

public final int getNumModules()

Returns the number of Modules in this collection.

getModule

public final Module getModule(int idx)

Returns the Module at index idx.

getModule

public final Module getModule(java.lang.String name)

Returns the Module with the specified name or null if such does not exist.

getModuleForPackage

public final Module getModuleForPackage(java.lang.String packageName)

Returns the Module for the specified package name or null if such does not exist.

getNormalizeName

public final int getNormalizeName()

normalizeName

public java.lang.String normalizeName(java.lang.String name,
                                      int maxLength)

Normalize name for the target database. Most importantly, make sure that its length does not exceed the allowed number of characters.

getTableExpr

public final TableExpr getTableExpr(java.lang.String tableName)

Returns the first found table expression for the given name or null if such does not exist.

See Also:

Module.getTableExpr(String)

getTableExpr

public final TableExpr getTableExpr(java.lang.Class<? extends Record> tableClass)

Returns the table expression for the given class or null if such does not exist.
