Method Detail

getBooleanProperty

public static boolean getBooleanProperty(java.util.Map<java.lang.String,java.lang.String> properties,
                                         java.lang.String name,
                                         boolean defaultValue)

convertToClass

public static java.lang.Object convertToClass(java.lang.String value,
                                              java.lang.Class<?> clazz)

Converts a value to the type of the given field.

Parameters:

value -

field -

Returns:

applyProperty

public static void applyProperty(java.lang.Object configuration,
                                 java.lang.String key,
                                 java.lang.String stringValue)

applyProperties

public static void applyProperties(java.lang.Object configuration,
                                   java.util.Map<java.lang.String,java.lang.String> properties,
                                   java.lang.String namingStrategy)

Sets an objects fields via reflection from String values. Depending on the field's type the respective values are converted to int or boolean. This method allows to specify a property naming strategy, i.e., if a property is written in camelCase, kebab-case, or snake_case.

Parameters:

configuration -

properties -

namingStrategy - can be either KEBAB_CASE, SNAKE_CASE, or CAMEL_CASE.

Throws:

ProcessEngineException - if a property is supplied that matches no field or if the field's type is not String, nor int, nor boolean.

applyProperties

public static void applyProperties(java.lang.Object configuration,
                                   java.util.Map<java.lang.String,java.lang.String> properties)

Sets an objects fields via reflection from String values. Depending on the field's type the respective values are converted to int or boolean.

Parameters:

configuration -

properties -

Throws:

ProcessEngineException - if a property is supplied that matches no field or if the field's type is not String, nor int, nor boolean.

resolveProperty

public static java.lang.String resolveProperty(java.util.Properties props,
                                               java.lang.String original)

Replaces Ant-style property references if the corresponding keys exist in the provided Properties.

Parameters:

props - contains possible replacements

original - may contain Ant-style templates

Returns:

the original string with replaced properties or the unchanged original string if no placeholder found.

convertToCamelCase

protected static java.lang.String convertToCamelCase(java.lang.String value,
                                                     java.lang.String token)
