+# Resource Stream Support
+
+* `ResourceStream` utility to provide a `Stream<Resource>` which traverses the resource and it's children
+* Fluent interface for creation of a `Predicate<Resource>` for use with Collections and Streams
+* Predefined predicates for Resources and Properties
+* Script support for creation of a complex `Predicate<Resource>` for use with Collections and Streams
+
+Example of a stream.
+
+```java
+ResourceStream
+ .from(resource)
+ .stream(
+ where(property("jcr:primaryType").is("cq:Page")))
+ .filter(
+ aChildResource("jcr:content")
+ .has(property("sling:resourceType")
+ .isNot("sling/components/page/folder")));
+```
+
+same results using the filter script
+
+```java
+ResourceStream
+ .from(resource)
+ .stream("[jcr:primaryType] == 'cq:Page'")
+ .filter(new ResourceFilter("[jcr:content/sling:resourceType] != 'apps/components/page/folder'"));
+```
+
+
+
+## ResourceFilter Script
+
+### Operators
+
+| Name | Comparison Type | Description |
+| --------- | --------------- | -------------------------------- |
+| and | NA | Logical AND |
+| && | NA | Logical AND |
+| or | NA | Logical OR |
+|||| NA | Logical OR |
+| == | String | Equal operator for Strings |
+| < | Number | Less than operator for Numbers |
+| <= | Number | Less than or equal operator for Numbers |
+| > | Number | Greater than operator for Numbers |
+| >= | Number | Greater than or equal operator for Numbers |
+| != | String | Is not equal to for Strings |
+| less than | Number | less than operator for Numbers |
+| greater than| Number | greater than operator for Numbers |
+| is | String | Equal operator for Strings |
+| is not | String | Is not equal operator for Strings |
+| like | String - Regex | Regex match against String |
+| like not | String - Regex | Regex match against String |
+| contains | String[] | String[] | String[] contains all of items |
+| contains not | String[] | String[] does not contain all of the items |
+| contains any | String[] | String[] contains at least one of items |
+| contains not any | String[] | String[] does not contain any of the items |
+### Logical Operators
+The 'and' and 'or' operators are logical operators that string together conditions. 'And' operators take precedence. 'Or' operators evaluate from left to right
+
+
+### Values
+
+Values for comparison are obtained through multiple methods
+
+| Method | Description |
+| ---------- | ---------------------------------------- |
+| Literal | Single(') or double (") quoted text in the query will be interpreted as a String. Boolean values of *true* and *false* will be translated to a String. |
+| Property | A String between square brackets '[',']'s will be interpreted as a property value and will be retrieved from the Resource using the get method |
+| Function | A string followed by parens containing an optional comma separated list of values. |
+
+### Types
+All types are converted to either a String or a Number. For direct equivalence the comparison is done as a String. For relational comparisons the object will be adapted to a number.
+
+### Dates/Instants
+Dates are a special, there are multiple ways to enter a date.
+
+In line, as part of the query, a date can be identified as a string that conforms to a standard ISO-8601 date time.
+
+> '2013-08-08T16:32:59.000'
+>
+> '2013-08-08T16:32:59'
+>
+> '2013-08-08T16:32'
+
+Are all valid date representations that are defaulting to the UTC timezone.
+
+For a ISO8601 date with timezone offset use the date function.
+
+> date('2013-08-08T16:32:59.000+02:00')
+
+If you need a different date format then the date function can accommodate that
+
+> date('2013-08-08','yyyy-MM-dd')
+
+Or you can add your own custom Function
+
+Dates are transitionally represented as a java.util.Instant which is then converted to a String in ISO-8601 format or as a Long number based on the type of comparison. The number representing the time in milliseconds since the EPOCH UTC region
+
+### Functions
+
+Functions provide the ability to add additional functionality to the Filter language. A Function is written in the format
+
+> string '(' comma, separated, list() ')'
+
+All functions MUST return either a String, a Number, or an Instant. Strings are assumed to be using the default UTF encoding.
+
+OOTB Functions are:
+
+| Name | Arguments | Returns | Description |
+| ---- | --------- | ------- | ----------------------------------- |
+| name | none | String | Provides the name of the resource |
+| date | 0 - 2 | Instant | First argument is string representation of the date, second argument is a standard Java DateFormat representation of the value. No argument returns the current time. |
+| path | none | String | path of the tested resource |
