Deprecated. Use suggestVariableNames(int, int, String, IJavaProject, int, String[], boolean) instead with VK_LOCAL as variable kind.

Suggest names for a local variable. The name is computed from variable's type and possible prefixes or suffixes are added.

If the type of the local variable is TypeName, the prefix for local variable is pre and the suffix for local variable is suf then the proposed names are preTypeNamesuf and preNamesuf. If there is no prefix or suffix the proposals are typeName and name.

This method is affected by the following JavaCore options : JavaCore.CODEASSIST_LOCAL_PREFIXES and JavaCore.CODEASSIST_LOCAL_SUFFIXES.

For a complete description of these configurable options, see getDefaultOptions. For programmaticaly change these options, see JavaCore#setOptions().

Parameters:
javaProject - project which contains the variable.
packageName - package of the variable's type.
qualifiedTypeName - variable's type.
dim - variable's dimension (0 if the variable is not an array).
excludedNames - a list of names which cannot be suggested (already used names). Can be null if there is no excluded names.
Returns:
char[][] an array of names.

String baseName,
                                            
IJavaProject javaProject,
                                            int dim,
                                            
String[] excluded,
                                            boolean evaluateDefault)
Suggests names for a variable. The name is computed from a base name and possible prefixes or suffixes are added.

The base name is used to compute the variable name. Some different kinds of base names are possible and each kind is associated to a different heuristic to compute variable names.
The heuristic depends also on the kind of the variable. Each kind of variable is identified by a constant starting with VK_.
When a prefix and a suffix can be added then all combinations of prefix and suffix are suggested. If the name is name, the prefix is pre and the suffix is suf then the suggested names will be prenamesuf, prename, namesuf and name.

The different kinds of base names are:

  • BK_NAME: the base name is a Java name and the whole base name is considered to compute the variable names. A prefix and a suffix can be added.
    There is a heuristic by variable kind.
    • VK_PARAMETER, VK_LOCAL, VK_INSTANCE_FIELD and VK_STATIC_FIELD:
      In this case the first character will be converted to lower case and the other characters won't be changed.
      If the base name is SimpleName then the suggested name will be simpleName.
    • VK_STATIC_FINAL_FIELD :
      In this case all letters of the name will be converted to upper case and words will be separated by an underscore ("_").
      If the base name is SimpleName then the suggested name will be SIMPLE_NAME.
  • BK_TYPE_NAME: the base name is a Java simple type name (e.g. HashMap) and all the words of the base name are considered to compute the variable names. A prefix and a suffix can be added to these names.
    There is a heuristic by variable kind.
    • VK_PARAMETER, VK_LOCAL, VK_INSTANCE_FIELD and VK_STATIC_FIELD:
      In this case a variable name will contain some words of the base name and the first character will be converted to lower case.
      If the type is TypeName then the suggested names will be typeName and name.
    • VK_STATIC_FINAL_FIELD :
      In this case a variable name will contain some words of the base name, all letters of the name will be converted to upper case and segments will be separated by a underscore ("_").
      If the base name is TypeName then the suggested name will be TYPE_NAME and NAME.
Some other kinds could be added in the future.

Each variable kind is affected by the following JavaCore options:

For a complete description of these configurable options, see JavaCore.getDefaultOptions(). To programmatically change these options, see JavaCore.setOptions(java.util.Hashtable) and IJavaProject.setOptions(java.util.Map)

Proposed names are sorted by relevance (best proposal first).
The names are proposed in the following order:

  1. Names with prefix and suffix. Longer names are proposed first
  2. Names with prefix. Longer names are proposed first
  3. Names with suffix. Longer names are proposed first
  4. Names without prefix and suffix. Longer names are proposed first

Parameters:
variableKind - specifies what type the variable is: VK_LOCAL, VK_PARAMETER, VK_STATIC_FIELD, VK_INSTANCE_FIELD or VK_STATIC_FINAL_FIELD.
baseNameKind - specifies what type the base name is: BK_NAME or BK_TYPE_NAME
baseName - name used to compute the suggested names.
javaProject - project which contains the variable or null to take into account only workspace settings.
dim - variable dimension (0 if the field is not an array).
excluded - a list of names which cannot be suggested (already used names). Can be null if there are no excluded names.
evaluateDefault - if true, the result is guaranteed to contain at least one result. If false, the result can be an empty array.
Returns:
String[] an array of names.
