groovy.lang.GroovyObjectSupport
org.freeplane.plugin.script.proxy.Convertible

All Implemented Interfaces:
  `groovy.lang.GroovyObject`, `Convertible`

public class Convertible extends groovy.lang.GroovyObjectSupport implements Convertible
Utility wrapper class around a String that is used to convert node texts to different types. It's especially important for Formulas.

## Constructor Summary

Constructor
Description
`Convertible(Object object)`
Use `toString(Object)` to convert to String, i.e.
`Convertible(String text)`
Use the `text` unchanged, i.

## Method Summary

Modifier and Type
Method
Description
`boolean`
`asBoolean()`
For implicit conversion to boolean: true if the text is not empty.
`int`
`compareTo(Object string)`
`int`
`compareTo(Convertible convertible)`
`boolean`
`equals(Object obj)`
`boolean`
`getBool()`
parses the text (case insensitive) as boolean via `Boolean.parseBoolean(String)`.
`Calendar`
`getCalendar()`
Converts to Calendar if possible.
`Date`
`getDate()`
Converts to Date if possible.
`Number`
`getNum()`
Convert to Number.
`Number`
`getNum0()`
Safe variant of `getNum()`, throws nothing - on any error (long) 0 is returned.
`Object`
`getObject()`
Uses the following priority ranking to determine the type of the text: null Long Double Date String
`String`
`getPlain()`
Removes HTML markup if necessary.
`Object`
`getProperty(String property)`
pretend we are a String if we don't provide a property for ourselves.
`Object`
`getRaw()`
Returns original object
`String`
`getString()`
No conversion.
`String`
`getText()`
No conversion.
`Convertible`
`getTo()`
Allow statements like this: `node['attr_name'].to.num`.
`URI`
`getUri()`
Converts to URI if possible.
`int`
`hashCode()`
since equals handles Strings special we have to stick to that here too since equal objects have to have the same hasCode.
`Object`
`invokeMethod(String name, Object args)`
pretend we are a String if we don't provide a method for ourselves.
`boolean`
`isDate()`
Type check.
`boolean`
`isNum()`
Type check.
`void`
`setProperty(String property, Object newValue)`
`String`
`toString()`

## Constructor Details

### Convertible

public Convertible(String text)
Use the `text` unchanged, i. e. oesn't evaluate formulas since this would require a calculation rule or NodeModel.

Parameters:
  `text` - the String to convert.

### Convertible

public Convertible(Object object)
Use `toString(Object)` to convert to String, i.e. conversion is done properly.

Parameters:
  `object` - the Object to convert

## Method Details

### getNum

public Number getNum() throws org.freeplane.plugin.script.proxy.ConversionException
Convert to Number. All Java number literals are allowed as described by `Long.decode(String)`

Specified by:
  `getNum` in interface `Convertible`
Returns:
  a Long or a Double, whatever fits best.
Throws:
  `org.freeplane.plugin.script.proxy.ConversionException` - if text is not a number.

### getNum0

public Number getNum0()
Safe variant of `getNum()`, throws nothing - on any error (long) 0 is returned.

Specified by:
  `getNum0` in interface `Convertible`
Returns:
  a Long or a Double if text is convertible to it or 0 otherwise (even if text is null).

### getString

public String getString()
No conversion.

Specified by:
  `getString` in interface `Convertible`
Returns:
  The original string.

### getText

public String getText()
No conversion.

Specified by:
  `getText` in interface `Convertible`
Returns:
  The original string.

### getPlain

public String getPlain()
Removes HTML markup if necessary.

Specified by:
  `getPlain` in interface `Convertible`
Returns:
  The result of `HtmlUtils.htmlToPlain(String)`

### getDate

public Date getDate() throws org.freeplane.plugin.script.proxy.ConversionException
Converts to Date if possible. The valid date patterns are "yyyy-MM-dd HH:dd:ss.SSSZ" with optional '-', ':'. ' ' may be replaced by 'T'.

Specified by:
  `getDate` in interface `Convertible`
Returns:
  a Date for the parsed text
Throws:
  `org.freeplane.plugin.script.proxy.ConversionException` - if the text is not convertible to a Date.

### getCalendar

public Calendar getCalendar() throws org.freeplane.plugin.script.proxy.ConversionException
Converts to Calendar if possible. See `getDate()` for recognized patterns.

Specified by:
  `getCalendar` in interface `Convertible`
Returns:
  a Calendar for the parsed text.
Throws:
  `org.freeplane.plugin.script.proxy.ConversionException` - if the text is not convertible to a Date.

Converts to URI if possible.

Specified by:
  `getUri` in interface `Convertible`
Returns:
  a URI
Throws:
  `org.freeplane.plugin.script.proxy.ConversionException` - if the text is not convertible to a URI.

### getObject

public Object getObject()

1. null
2. Long
3. Double
4. Date
5. String
