coerceToInteger

public static java.lang.Integer coerceToInteger(java.lang.Object obj)
                                         throws AspException

Coerces a data type into an Integer type.

• null = 0
• undefined = 0
• Integer = self
• Double = Cast to integer
• String = Parsed to integer, errors are passed through
• Everything else causes a AspCastException

---

coerceToString

public static java.lang.String coerceToString(java.lang.Object obj)
                                       throws AspException

Coerces an object to a string.

• null = ""
• undefined = ""
• String = self
• Integer = cast to string
• Boolean = cast to "true"/"false"

---

coerceToBoolean

static java.lang.Boolean coerceToBoolean(java.lang.Object obj)
                                  throws AspException

Converts a data object to a boolean type.

• null = false
• undefined = false
• Boolean = self

---

coerceToDouble

static java.lang.Double coerceToDouble(java.lang.Object obj)
                                throws AspException

Casts an object to a double value.

• null - 0.0
• undefined - 0.0
• Double - self
• Integer - Casted to double
• String - Parsed to double

---

coerceToDate

static AspDate coerceToDate(java.lang.Object obj)
                     throws AspException

Coerces a data value to a Date value.

• Date - Self

---

coerceToNode

static java.lang.Object coerceToNode(java.lang.Object obj)
                              throws AspException

Coerces an object to a "node". All of the known base types (Integer, Boolean, Double, String) are left as-is, but other Java objects are wrapped into a JavaObjectNode-type class to handle ASP->Java calls.

• null - null
• Node - self
• Double - self
• Integer - self
• Boolean - self
• Byte - self
• String - self
• SimpleMap + SimpleReference - Wrapped in a JavaReferenceMapNode
• SimpleMap - Wrapped in a JavaMapNode
• SimpleReference - Wrapped in a JavaReferenceNode
• Other - Wrapped in a JavaObjectNode

---

integerFromHex

public static java.lang.Integer integerFromHex(java.lang.String str)

Obtains an integer value from a hex string line &FF.

---

isNumber

public static boolean isNumber(java.lang.Object obj)
                        throws AspException

Determines if this object is a number.

---

dereference

public static java.lang.Object dereference(java.lang.Object obj)
                                    throws AspException

Derefernces the given object. If the object is a SimpleReference object, it will dereference it, and keep dereferencing it until a non-SimpleReference object is found.

---

isDate

public static boolean isDate(java.lang.Object testObject)

This function tests an object to see if it is a date object.
